(Submitter supplied) Our goal was to identify gene expression and functional differences between directly reprogrammed vascular cells derived from young and old individuals, as wells as from healthy and Hutchinson-Gilford Progeria Syndrome (HGPS) donors. We provided a full characterization of reprogrammed endothelial and smooth muscle cells by comparing their gene expression with both the original fibroblasts and primary vascular cells, showing that reprogrammed cells express key vascular cell-identity genes and contribute to the formation of in vitro 3D vascular structures. more...

(Submitter supplied) To model Hutchinson-Gilford Progeria syndrome (HGPS), we differentiated patient-derived induced pluripotent stem cells (iPSCs) to vascular smooth muscle cells (VSMCs). We then performed gene expression profiling analysis using data obtained from RNA-seq of the serially passaged cells at passage7 and passage 14.

(Submitter supplied) Hutchinson Gilford Progeria Syndrome (HGPS) is a rare, sporadic genetic disease caused by mutations in the nuclear lamin A gene. In most cases the mutation creates an efficient donor-splice site that generates an altered transcript encoding a truncated lamin A protein, progerin. In vitro studies have indicated that progerin can disrupt nuclear function. HGPS affects mainly mesenchymal lineages but the shortage of patient material has precluded a tissue-wide molecular survey of progerin’s cellular impact. more...

(Submitter supplied) Hutchinson-Gilford Progeria Syndrome (HGPS) is a segmental premature aging disorder caused by the accumulation of the truncated form of Lamin A known as Progerin within the nuclear lamina. Cellular hallmarks of HGPS include nuclear blebbing, loss of peripheral heterochromatin, defective epigenetic inheritance, altered gene expression, and senescence. To model HGPS using iPSCs, detailed genome-wide and structural analysis of the epigenetic landscape is required to assess the initiation and progression of the disease.

(Submitter supplied) Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal human premature aging disease1-5, characterized by premature atherosclerosis and degeneration of vascular smooth muscle cells (SMCs)6-8. HGPS is caused by a single-point mutation in the LMNA gene, resulting in the generation of progerin, a truncated mutant of lamin A. Accumulation of progerin leads to various aging-associated nuclear defects including disorganization of nuclear lamina and loss of heterochromatin9-12. more...

Analysis of iPSCs generated from fibroblasts from patients with Hutchinson-Gilford progeria syndrome (HGPS), a rare and fatal premature aging disease. Premature aging was recapitulated by differentiation of the HGPS-iPSCs. Results provide insight into molecular mechanisms underlying premature aging.

(Submitter supplied) Vascular dysfunction is one of the typical characteristics of aging, but its contributing roles to systemic aging and the therapeutic potential is lacking experimental evidence. Accumulating data suggest that the mechanisms underlying aging are similar to those governing Hutchinson-Gilford progeria syndrome (HGPS), a premature aging disease, in which affected patients succumb to cardiovascular diseases (CVDs). more...

(Submitter supplied) Purpose: Arterial stiffening is a hallmark of premature aging in Hutchinson-Gilford Progeria Syndrome (HGPS), but the molecular regulators remain unknown. Here, we show that the LMNAG609G mouse model of HGPS recapitulates the premature arterial stiffening seen in human HGPS. To gain a better understanding of potential stiffness-regulators in LMNAG609G mice, we performed RNA-sequencing analysis on cleaned descending aortas from 2- and 24-month WT and 2-month LMNAG609G mice on a C57BL6 background. more...

(Submitter supplied) Hutchinson–Gilford progeria syndrome (HGPS) is a rare genetic disease with widespread phenotypic features resembling premature aging. HGPS was recently shown to be caused by dominant mutations in the LMNA gene, resulting in the in-frame deletion of 50 amino acids near the carboxyl terminus of the encoded lamin A protein. Children with this disease typically succumb to myocardial infarction or stroke caused by severe atherosclerosis at an average age of 13 years. more...

(Submitter supplied) The functional decline of the vascular niches is linked to several disorders, including neurodegeneration and bone loss. However, the causes of this decline are poorly understood. A key signature of aging is the progressive damage of the microvasculature, but a clear picture of its determinants and therapeutic targets in a human context is lacking. We designed/validated a novel approach based on long-living human microvascular networks to study the age-dependent modulation of the endothelium by microenvironment and serum. more...
